农村清洁供暖对大气环境质量的影响评价及预测

Evaluation and prediction of impact of clean heating on atmospheric environmental quality in rural areas

为评价农村地区清洁供暖对大气环境质量的影响,建立了供暖排放对大气环境质_量影响的因子模型(A-H模型),分析了清洁供暖对京津冀及周边地区空气质量的影响程度。结果表明,京津冀及周边地区实施清洁供暖可以将供暖季细颗粒物PM2.5质量浓度降低约20μg/m^(3);综合考虑人口、建筑面积、清洁能源等发展趋势,预测2030年京津冀及周边地区供暖季PM2.5浓度将显著降低。

In order to evaluate the impact of clean heating on air quality in rural areas,establishes а factor model(A-H model)of the impact of heating emission on atmospheric environmental quality.Analyses the impact of clean heating on air quality in Beijing-Tianjin-Hebei area and its surrounding areas.The results show that the implementation of clean heating in above areas can reduce the mass concentration of fine particulate matter PM2.5 in heating season by about 20μg/m^(3).Comprehensively considering the development trends of population,building area and clean energy,predicts that the concentration of PM2.5 in the heating season of Beijing-Tianjin-Hebei area and its surrounding areas will be significantly reduced in 2030.
